Collisions of low-energy antiprotons with molecular hydrogen: ionization, excitation and stopping power
A time-dependent coupled-channel approach was used to calculate ionization, excitation, and energyloss cross sections as well as energy spectra for antiproton and proton collisions with molecular hydrogen for impact energies 8<E< 4000 keV.
متن کاملIonization of hydrogen and hydrogenic ions by antiprotons.
Presented here is a description of the ionization of hydrogen and hydrogenic ions by antiproton-impact, based on very large scale numerical solutions of the time-dependent Schrödinger equation in three spatial dimensions and on analysis of the topology of the electronic eigenenergy surfaces in the plane of complex internuclear distance. Comparison is made with other theories and very recent mea...
متن کاملStopping power of antiprotons in H, H2, and He targets
The stopping power of antiprotons in atomic and molecular hydrogen as well as helium was calculated in an impact-energy range from 1 keV to 6.4 MeV. In the case of H2 and He the targets were described with a single-active electron model centered on the target. The collision process was treated with the close-coupling formulation of the impact-parameter method. An extensive comparison of the pre...
متن کاملCollisions of low-energy antiprotons and protons with atoms and molecules
Antiproton (p̄) collisions have evolved to a powerful tool for the testing of dynamic electron correlations in atoms and molecules. While advances in the understanding of p̄ collisions with the simplest oneand two-electron atoms, H and He, have been achieved experiment and theory did not agree for low-energy p̄ + He collisions (< 40 keV), stimulating a vivid theoretical activity. On the other hand...
متن کاملExcitation Functions of Stopping Power and Flow in Relativistic Heavy-Ion Collisions
Using a relativistic transport (ART) model, we study the stopping power, the formation of superdense hadronic matter as well as the strength of transverse and radial flow in central Au+Au collisions at beam momentum from 2 to 12 GeV/c per nucleon. We find that complete stopping is achieved in the whole beam momentum range. In particular, the proton rapidity distribution scaled by the beam rapid...
